What s going on with my computer teacher automatically shutting down?

Hello, first of all, use your hand to test whether it is very hot or windy at the exhaust vent. If it is very hot and windy, it proves that your notebook workload is indeed large, and the heat dissipation is not good, processing: clean up the dust, add the heat dissipation base.

If there is no wind, treatment: clean up the dust, check the fan, replace the fan. Good luck.

How long has the computer been used? The boot fan is not noisy.

Can you elaborate a little more?

There are a variety of possibilities for automatic shutdown, the more common ones are:

1. Due to the long use of the computer and the poor cooling function of the main box, the temperature of the inverted CPU and graphics card is too high, and it suddenly shuts down and restarts after playing for a long time.

2. Because of the computer virus, it is best to kill the virus first...

3. It is the least common that there is a problem with the power supply of the host, or that there is a problem with the plugging side.

Do you look at the electric fan of the main chassis and still turn?

If it doesn't work, just restore it with one click:

A few seconds after booting in, after the motherboard brand came out, I saw a series of English prompts, and immediately pressed "F11" You use "one-click restore", if not, you have to reinstall the system.

It is recommended that you install and use Master Lu to test the body temperature of each component of the host, and it can also be optimized.

Try reinstalling the system, if it reboots as usual, it is mostly a hardware failure.

The computer shuts down automatically for no reason.

1. Check whether the CPU is overheated and whether the CPU fan holder is stable, if it is broken.

Or it is unstable, the CPU fan cannot be suppressed, the CPU fan has insufficient heat dissipation capacity, and the CPU temperature is too high, and the motherboard's automatic protection function will automatically shut down.

2. The capacitor of the motherboard is deformed, and the deformation may be caused by the unstable voltage of the host, so it can be replaced.

3. When the power supply of the host fails, or the voltage fluctuates greatly, the AC regulated power supply can be added.

4. No, it is recommended to use 360 Antivirus 360 Security Guard to repair it in safe mode, and it is not possible to disconnect the network and reinstall the system to eliminate system problems.

Hello Eliminate problems with indoor voltage and socket quality.

The shutdown is mainly caused by insufficient power of the power supply or high hardware temperatureThe power supply is not enough to replace the power supply (the market price of ordinary power supply is 80 yuan, and the better one will be more expensive) The temperature (graphics card temperature, motherboard temperature and other hardware) is too high The motherboard protects itself, so the shutdown solution: coat the CPU with a layer of silicone that is, heat dissipation glue The market price is 2 yuan, and at the same time, clean up the dust of the CPU fan.

Lubricate the fan shaft.

Not yet to replace the fan.

The solution is these, if you don't understand the specifics, you can hi me to talk about it in detail——— drifting with the wind.

1.It may be a heat dissipation problem of the computer, see if the cooling fan is normal, open the case and let the computer run for a period of time, to see if there will be a shutdown phenomenon, if you open the case is fine, it is a heat dissipation problem, and you need to change the fan to strengthen the heat dissipation.

2.If you have a computer system problem, try reinstalling your computer system.

3.If there is a problem with the power supply, try replacing the power supply.

Hope it helps!

Change the memory and see if it works.

There are many reasons for automatic computer shutdown, and there are generally the following points.

1. Viral infection.

2. The CPU temperature is too high, the protective restart, and now the temperature is high in summer, and the fan has problems, which is very likely to cause such failures.

3. Poor memory performance.

4. The power supply performance of the host is poor, and the host will automatically restart when the host load is large or the grid voltage is low5. The power grid voltage fluctuates, and others will cause the host to automatically restart when they enable high-power electrical appliances or poor contact with the power supply line.

Estimate that there is a problem with the voltage in your home.

You see, whether it is a heating problem, pay attention to heat dissipation.

Sudden shutdown of the computer solution:

Take out the battery of the motherboard, buckle it back, and discharge it. Purpose: To restore the default value of the BIOS's residual judgment settings, and to eliminate the phenomenon of automatic restart or shutdown of the BIOS's cooling preset.

2.Sweep the dust inside the chassis to eliminate short circuits or poor heat dissipation caused by excessive dust.

3.Silicone grease is used to improve heat dissipation capacity, if there is no silicone grease, the heat may not be dissipated, and the machine will automatically shut down. Note:

If there is too much thermal grease and it is too thick, it will form a film in the middle of the contact surface, which will hinder the direct contact of the metal, which is worse than not applying thermal grease.

4.Think about it, is the fan size or fan power enough for a high-end computer? First consider the size of the fan (the bigger the better), then the power (the bigger the better), and the manufacturer.

5.Other objective reasons, such as high indoor temperature, running large programs (games) for a long time when booting, poor heat dissipation of the case, poisoning, CPU usage often 100, etc. You can install Windows Optimizer, in addition to the software can comprehensively clean and optimize the system, it can also detect all hardware and software information of the system, you can detect it at any time, and compare it with the previous information, from which you can find problems.

It is generally caused by the following reasons:

1. The power supply is broken, or new hardware has been added, and the power supply is insufficient.

2. The graphics card or graphics card fan is broken.

3. The motherboard is broken, and the motherboard has a short circuit.

Solution: 1. If the computer has an independent graphics card and the power supply is not enough, then you can only change to a higher power power supply.

2. Turn off the computer, touch the south bridge, north bridge chip and graphics card chip of the motherboard with your hands, if it is very hot, it is likely to be broken and need to be repaired.

Generally, the automatic shutdown may be caused by the high temperature caused by too much dust in the CPU fan, if so, clean up the dust of the CPU fan and heat sink, and add new heat dissipation silicone grease. If it is not a problem, it may be caused by problems with motherboard parts or power supply, voltage instability, hard disk failure, etc., and the new hardware is not compatible. In addition, a Trojan horse can also cause a shutdown due to a system failure, but the probability of this is very small, restore the system or try to reinstall it.

If it automatically shuts down or standby without operation, it may be a problem with the settings. Right-click on the desktop to select Properties Screen Saver Power Supply Select a scenario that suits you from the drop-down list in Power Usage Scenarios, and set Never in the list of Monitor Off, Hard Disk Off, System Standby, and so on below (or set a suitable time).

Open the control panel All Control Panel Items Power Options Select Turn off the monitor (select Never or Set Time) Select Never or select the appropriate time from the drop-down list next to Make the computer go to sleep (Win7 system).

See if it's caused by the settings below.

Let's see if you have any settings? If not! You go check it out! See if the computer is poisoned or something! If it still doesn't work! Just reinstall the system!
